redshift

Adjust the color temperature of your screen according to your surroundings. More information: http://jonls.dk/redshift.

• Turn on Redshift with 5700K temperature during day and 3600K at night:
  redshift -t {{5700}}:{{3600}}
• Turn on Redshift with a manually specified custom location:
  redshift -l {{latitude}}:{{longitude}}
• Turn on Redshift with 70% screen brightness during day and 40% brightness at night:
  redshift -b {{0.7}}:{{0.4}}
• Turn on Redshift with custom gamma levels (between 0 and 1):
  redshift -g {{red}}:{{green}}:{{blue}}
• Turn on Redshift with a constant unchanging color temperature:
  redshift -O {{temperature}}
